SPECIFICATIQN` forming part of Letters Patent No. 525,401, dated Septemberl, 1894.

Application filed October Z4, 1893- Serial No. 489,005. (No model.)

To all whom t may concern:

Be it known that I, JOHN J. BREWIS, a citizen of the United States,residing at Chicago, Illinois, have invented certain new and usefullmprovements in Stone-Crushers, of which the following is a specification.

My invention relates particularly to the method of operating the crushing mechanism and the transmission of power for same to auxiliary mechanisms which may be'located adjacent to the stone crusher; and has for its object the providing of suitable mechanism and attaching it to the crusher frame, so that it nay be operated directly by the mechanism which operates the crusher; and it consists in the features, combinations and details hereinafter described and claimed.V

In the drawings, Figure lis a vertical elevatlon, partly in section, showing myimproved mechanism engaging with and adapted to be operated by the driving mechanism yof the crusher; and Fig. 2- a horizontal transverse section, taken on line 2 of Fig. l looking in the direction of the arrow. In theuse of stone Crushers, especially that class provided with gyrating shafts and crushing heads, it is customary to drive the bev-V eled gear attached to the gyrating shaft by means of a beveled pinion inserted through..

an opening in the crusher frame at a point opposite and 1n line with the discharge opening. The line shaft for driving the shaft which carries this beveled pinion is generally located parallel therewith, so that when it is neces-` sary to drive auxiliary mechanism, which has its operating shaft at right angles to the driving shaft for operating the crushing mechanism, beveled gears are generally employed, one attached to the outer end of the shaft carrying the driving mechanism, and the other toa supplemental shaft, bot-h supported by framework attached to and supported by the base which supports the driving mechanism, or a quarter turn belt is interposed between the line shaft and the auxiliary mechanism. This mechanism has been found to be cumbersome fand expensive in construction.

My improvement is designed to obviate v these objections, and to provide a simpler and more efficient method of accomplishing the same, doing away with the necessity of a base for supporting the framework of either the driving or driven mechanisms, and to provide means by which auxiliary mechanism may be operated through a shaft which has a gear engaging directly with the driving mech'- anism of a gyrating shaft, which,in a measure, lServes to balance the forces which tend to wear the driven gear unequally.

In constructing my improvement, I use a crusher frame, A, containing crushing moch-l anism, preferably of the class' known as the gyrating type, provided lwith the usual gyrating shaft, a, having the crushing mechanism of thewell knownform at the top; but asthis forms no particular portion of my invention, I do not deem it necessary to describe it fully in detail. The non-gyratory revolving sleeve, in the eccentric bore of which is carried the lower end of the gyratory shaft, a, is provided with a beveled gear wheel, a', the rotation of which gyrates such shaft, and is adapted to be operated by t-he driving mechanism. The lower portion of the crusher frame is provided preferably with four openings. crushed material, B, is provided with aninclineddiaphragm or chute, b, and openings 00 and C2, are located preferably at equidistantpoints around the circumference of the crusher frame and adjacentl to the beveled gear on the gyrating shaft. Secured preferably to the crusher frame, and in line with the opening, C', directly opposite the discharge opening isla bracket, D, provided with bearings in which is mounted a driving shaft, d, having its inner end provided with a beveled pinion, E, engaging with the beveled gear on the gyrating shaft, in such manner that the rotation of the driving shaft is imparted through the beveled. gears and caused to operate the gyrating shaft. The shaft, d, may be supplied with an ordinary driving pulley, d', or an ordinary spur gear may be used in place of the driving pulley and operated by a suitable train of gears to multiply thepower or speed used for operating the crushing mechanism. The bracket D, may be secured to the crusher frame by bolts or nuts, or in any other well known manner.

To transmit the power for driving auxiliary IOO mechanism through the driving shaft and mechanism for operating the ,gy-rating shaft,

ing at its inner end a beveled pinion, t', enl gaging with and adapted to be operated by the rotations of the beveled gear on the gyrating shaft. The outside end of the hollow shaft is provided with a shoulder, fi', to takeup orlimit the endwise motion of such shaft.

erablya solid shaft, K, which may be provided with a featherrk, engaging with a` corresponding feather-way in the hollow shaft so as toimpar-t the rotation` of thel hollow shaft tothe shaft, K. A set` screw, 7c', is inserted through the shoulder of the hollow shaftso` as to impinge against theA shaft, K, and prevent endwse motion of thesame---the` power beingf impartedlwholly through the feather tothe feather-way.` The shaft, K, is providedU at its outer endiwith a pulley, o2,which may be used to drive a belt engaging with any outside mechanism.

While I have describedzfullyin:detail. this` hollowfshaft with its engagingzshatt, I do not `deem this necessary forthe ca'rryiingk out of my improvemenaas this mechanism is. iutendedtoxbe used inA such cases where it may be deemed" necessary tov leave` the' beveled: pinion, z', in engagement withuthergear ou the gyrating shaft, andnot to leave any mecham ism projecting outward so as tobe in the way of other mechanisms.

driving and operating the gyrating shaft, I dol not desire to be understood as claiming this as my invention, as I believe it to be the invention of other parties.
